This is a binary clock that was built into a 3d-printed case created in Minecraft. It shows the current time in a binary coded decimal format. The code and idea are based on a tutorial by Daniel Andrade.

The model was exported with the free tool Mineways and printed on a Zprinter 650 3d-printer, with a block size of 125mm^3 (so every block has an edge length of 5mm).

17:07 (i.e. 5:07 PM)

After printing, LEDs were glued into the case after filing the openings a bit wider. Then, the LEDs were soldered to form a 4×4 LED matrix, and the matrix was connected to an Arduino board. Two pushbuttons were added for setting the clock (hours and minutes).
